How’s this then, for another example:

    M_CAT02 = new Matrix3([
         .7328,  .4296, -.1624,
        -.7036, 1.6975,  .0061,
         .0030,  .0136,  .9834])
    M_HPE = new Matrix3([
         .38971,  .68898, -.07868,
        -.22981, 1.18340,  .04641,
         .00000,  .00000, 1.00000])

Without lining those all up, it becomes a real pain in the butt to read the matrix.
